What to do if your computer or office chair squeaks

Reasons: why the computer chair starts to creak

• Screws are not securely fastened between parts or are not tightened properly even during production.
• The grease that was on the bearings and hinges has dried out.
• Due to poor quality parts or improper use, the holder broke. In this case, the purchase of additional spare parts or the help of specialists is required.
• The reason may also be ordinary dust, which has accumulated in cracks and prevents the mechanisms from working as intended. In this case, careful disassembly and cleaning of the chair will be useful.

Prevention

In order not to search on numerous sites and ask friends what to do if your computer or office chair creaks, it is better to prevent this problem in advance. It is wrong to neglect the rules for operating such furniture, believing that it is made reliably, and if something is wrong, then the manufacturer is to blame.

You need to know how to use chairs with moving parts correctly:

1. They should not be ridden unnecessarily, rocked or tilted too far back. You should also not spin around in your chair like on a carousel.
2. It is important to remember that there are weight limits that such furniture can withstand, so obese people need to choose special, stronger models.

If you don’t sit down in the chair from a running start, don’t swing on it and don’t overload it, you won’t have to think about how to repair it later. In addition, it is very important to regularly lubricate and inspect all mechanisms, tighten bolts and clean dust - then the product will serve for a long time and without failures.

How to repair or replace an office chair gas lift

A computer or office chair refers to furniture that, due to constant stress, is very susceptible to natural wear and tear. This factor, together with violations of operating conditions, is the most likely cause of a breakdown. How to make repairs? In what situations will it be necessary to replace the gas lift with a chair and how to do the work yourself? He answers further.

Replacing an office chair gas lift

Rocking mechanism

If the swing mechanism of an office chair squeaks during use, then most likely it is damaged or also requires tightening the bolts. Also, the reason may lie in dried grease; it often loses its properties even before the furniture arrives at the store.

Common swing mechanisms:

• multiblock - allows you to fix the inclination and rigidity of the backrest. You don’t have to check, it rarely makes a creak;
• knee mechanism - provides deep swing, it has two levers and an adjusting screw;
• top gun - the swing is adjusted by one lever; the top gun has an adjusting screw;
• piastra - a mechanism for adjusting the height of the chair with one control lever;
• permanent contact - responsible for adjusting the height and angle of the backrest, as well as seating depth. With spring base;
• spring-screw mechanism - attaches the backrest to the seat and is needed to regulate the rigidity of the backrest;
• slider - responsible for the depth of the seat (it can move back and forth, like in a car)

Almost all of them must be lubricated regularly. The most convenient way would be to use a special lubricant in a bottle. If replacement is required, it is better to contact your nearest service center, especially if there is a valid warranty.

If your office chair creaks, should you call a repairman or can you handle it yourself?

You can deal with the unpleasant noise of the chair yourself if the cause of such an accident is known. So, if you need to tighten the bolts, you can do it yourself using, depending on the design of the chair, a hex or small Phillips screwdriver.

Depending on the design of your computer chair, you will need to tighten the bolts in this area as far as possible:

• 2-3 on the armrests (located under the hoods);
• 4 on the swashplate;
• 4 on the back of the seat.

It is important not to overtighten the bolts when tightening. Twisting is performed all the way + control rotation, no more. Otherwise, you can “lick” the thread and break the mechanism or fastener.

If the bolts can no longer be tightened and are regularly unscrewed, it is recommended to use blue thread sealant.

A common squeak is a gas lift squeak. If you're sitting in a chair and hear a creaking or squeaking sound from underneath without a specific seat, it's probably due to the gas lift. To get rid of this sound, do the following:

• Let's turn over the office chair.
• From the back side of the gas lift strut (from the cross), the stop is removed using a flat screwdriver.

Fears that gas lift will catch up are not justified. Gas fittings do not break during disassembly; To deform it, you need to at least weld its rod to the rotating mechanism or hit it hard with a sledgehammer.

• Carefully lift the crossbar up. In this case, the gas lift column will be on the crossbar.
• Lubricate the bearing, support washers, gasket, and upper rubber washer. As a rule, it is the last element that causes an unpleasant squeak.

You can lubricate the parts separately, but it is important to remember the assembly sequence: the rubber seal is fixed only on the piston rod, then there is a support washer, a bearing + another washer. The rod itself is lubricated with low viscosity oil.

• We install the gas lift box, fix the rod with a washer and a latch.

Some gas lifts vary in configuration. Therefore, in one of them you can use rubber washers, but in the other there is nothing to be afraid of plastic washers.

An important operating rule: to prevent the office chair from squeaking, do not rock it when the mechanism is in a fixed position. In this case, the gas lift breaks and a creaking sound appears due to a malfunction.

What is the best way to lubricate?

To eliminate the unpleasant creaking of furniture today, a simple and affordable tool is used - WD-40. This product does not have an aggressive effect on the surface of parts, does not corrode the paint, and does not contribute to its fading. In some cases, you can first try to spray the spray without disassembling the mechanism. If the squeak does not go away, it is recommended to follow the above recommendations. This ends the self-removal of the squeak. If the unpleasant sound does not go away even after the manipulations, it is recommended to return the chair for repair.

Possible problems and errors

Problems with wheels on office chairs occur when they are used on hard surfaces. On parquet and laminate flooring, plastic rollers wear out quickly. They are more suitable for short-pile carpets. For hard floors, you should choose computer chairs with rubberized wheels. When choosing, you should pay attention to the elasticity of the seat material. It's worth trying to sit in it. If there is a dent left after standing up from it, it is not suitable for long-term use.

Gas elevator failures are most often associated with the fact that the maximum permissible load is exceeded by users. You should pay attention to this characteristic when purchasing a chair. Breakdowns and creaking of the gas lift may be associated with exceeding its service life. Most often, with careful use, a computer chair lasts no more than 10 years, after which the gas lift is replaced and you can continue to work in it.

The computer chair is creaking - what to do? How to rid yourself of discomfort

The computer chair served you faithfully, comfortably supported your back, moved silently around the room, but one day it began to squeak disgustingly. This is annoying and distracts from work. But do not rush to throw away the chair and buy a new one; very often the problem can be corrected at home without much expense.

In what places does it squeak?

LINK! Before you begin, place something on the floor to prevent dust.

First, detach the backrest from the chair to make it easier to turn and inspect. There is a large molded screw on the back, unscrew it and pull up on the holder - it will easily detach from the metal rail. Now unscrew the second screw under the seat and separate it from the L-shaped part. The resulting stool on wheels is now easier to do.

• If your office chair squeaks when you move, check the casters. Often small debris or dust that gets into the cracks makes an unpleasant sound. Dirt can be removed with a long narrow object or blown out with a can of compressed air.
• If you hear a squeaking sound when the chair rotates, the problem may be with the gas lift. This is the part responsible for adjusting the height of the chair, rotating around its axis and spring function (reducing the load when sitting on a chair). To inspect the gas lift, turn the chair over and look for the stop in the center of the crossbar. Remove the washer by lifting the tab, carefully remove the gas lift and lubricate the bearings, seals and other parts. If you still hear squeaking or clicking noises, the problem may be more serious and need to be replaced. A new gas elevator will still cost less than buying a whole chair.

• Many chairs have a “pain point”: the rocking mechanism. The chair is controlled by a plate, a spring screw, or a centering mechanism (you'll recognize it by the protruding handle). Often the problem is a broken plate weld. Inspect the fasteners and, if necessary, tighten the bolts with a screwdriver. It happens that after tightening the screws, they quickly unscrew again - here regular vinyl glue or any other will come to your aid - pour a few drops into the gap and tighten it well. Do not turn the structure upside down until the glue has completely dried.

• When you hear the L-shaped mechanism squeak when you change the position of the backrest, you need to remove the side corners by lifting them with a flat-head screwdriver - they are connected together by plastic clips, so proceed carefully so as not to damage them. Wipe the inside with a rag, add lubricant to the spring and replace the caps.
• If the armrests are loose, tighten the screws.
• Disassemble the rear part if it is the cause of the squeaking.

Instructions on how to disassemble the back of a chair

You have already disconnected the backrest from the chair and from the L-shaped piece.

The screws you are interested in are located at the bottom of the backrest; to access it, you need to pull the plastic cover up or assemble it with a thin, flat object.

Inside, a metal insert is usually attached to the plywood frame. It is necessary to check the reliability of fastening, tighten the screws if necessary and lubricate all suspicious places.

IMPORTANT! At any stage of disassembly, it is important not to overdo it. If something goes wrong, double check the part for fasteners and screws. Otherwise, you will waste time or break everything that needed to be unscrewed.

How to lubricate a chair

• It is most often recommended to lubricate squeaking parts with WD-40. Contains solvent and mineral oil to facilitate sliding and protect the surface from moisture. “Vedashka” is convenient to use at home, as it comes in the form of an aerosol and comes with a long narrow spout - for careful application to hard-to-reach places.
• You can use fat or Vaseline.
• Any hardware lubricant will do, such as what was previously used on door hinges or sewing machines.
• You should not take vegetable oil or cosmetics - even if there is an effect, it will not last long.

IMPORTANT! Most lubricants can have an unpleasant or even toxic odor.

Be sure to ventilate the room after using them.

Where does the squeak come from?

The design of a computer chair is a rather complex mechanism, so creaking can occur for various reasons and at any stage of operation. There is no need to rush to return the purchase back to the store; it is worth finding out the reasons and, if possible, eliminating them.

Among the main factors for the appearance of squeaking are often cited:

• weak tightening of bolts even at the assembly stage;
• abrasion or drying out of the lubricant of joints and bearings during operation;
• the parts of the chair were of poor quality, broken or damaged as a result of use;
• obstruction of dust and dirt from the operation of mechanisms in normal mode.

The creaking may appear at different times:

• when a person sits on a computer chair;
• if the chair turns or rocks.

Most often the sounds come from under the seat. Once you find out the location of the squeak and the cause, fixing the problem will not be so difficult.

Frame

The frame of a computer chair can make a creaking noise. The instructions for use recommend periodically tightening the bolts and checking the integrity of the mechanisms. This procedure should be carried out at least once every six months. In addition, it should be noted that the fasteners are put into place only after the chair has been used under full load. For this reason, after purchasing and using it for a couple of weeks, it is worth picking up a screwdriver or hex key and tightening the bolts. The main thing is not to overdo it, tighten it all the way and no more. If bolts are constantly loosened, experts advise using thread sealant.

Rocking mechanism

In addition to the frame, the computer chair may experience creaking in the rocking mechanism. The reason is also the weakening of the bolts or the fragility of the lubricant, which often dries out while computer chairs are in storage.

The entire swing mechanism consists of several parts:

• multiblock - almost never creaks, designed to fix the rigidity and tilt of the backrest;
• knee mechanism - needed for swinging, requires lubrication;
• top gun - rocking, has a screw for adjustment;
• permanent contact - regulates the angle of inclination of the back of a computer chair and its pressing against the back of the person sitting, has a spring included;
• slider - thanks to it, the planting depth can be adjusted.

All elements of the swing mechanism require periodic lubrication.

Back

Most often, the back of a computer chair creaks. To correct the situation, it is worth unscrewing the figured screw from the permanent contact and the screws attaching the plastic cover. The latter is carefully lifted up. After the fasteners come out, remove the cover. The metal insert must be secured with 4 bolts. Most likely, they are not screwed tightly or several of them are lost. By replacing and tightening the bolts, the squeaking situation can be corrected.

Fixing the defect yourself

After prolonged use, users notice that the chair begins to make grinding noises and other unpleasant sounds. What to do if your computer office chair squeaks depends on the root cause:

1. Most often the problem occurs when bolts are loosened. To correct the situation, you need to turn the chair upside down and, depending on the model, tighten all the fasteners with a screwdriver or hexagon until it stops. If some of them slip, you will need to remove the element, pour sealant or PVA into the hole and quickly screw the bolt back. After this, you cannot turn the chair upside down, much less use it, until the glue is completely dry.
2. To understand why the back of an office chair creaks, you need to remove it. This is not difficult to do: unscrew the screw and, lifting the element along the guides, pull it out. Next, you will need to remove the plastic trim from the back in the same way. Metal plates are bolted to the plywood frame. All of them must be checked and screwed well. If necessary, gaskets or sealant can be used. In addition, it is recommended to wipe dust from the back.
3. The swing mechanism of an office chair often creaks. You can get to it by removing the seat back. At the point where it connects to the seat, an L-shaped mechanism is installed, which is responsible for tilting. Dust accumulates there, so a squeaking sound is heard when rocking. The mechanism can be easily disassembled by removing it from the case, but it is important to remember the assembly order. After disassembly, it is cleaned of dirt and lubricated. To reassemble the furniture, follow all steps in reverse order.
4. A computer chair often squeaks due to the drying of the lubricant that covers all moving parts of such furniture. This substance is short-lived and sometimes even dries out during storage, so even a new product can squeak. Therefore, it will be useful for any user to know how to lubricate an office chair so that it does not creak. To do this, you can use any lubricant except grease. It is very convenient to use a special product in a can. It is better to first disassemble the mechanism, clean it of dust and remnants of old lubricant, and only then apply a new layer. To do this, it is not at all necessary to disassemble the chair completely. If the lubricant is in a can, you just need to spray it on all problem areas. But often this is not enough, since dust and dirt accumulate inside during operation.
5. If the seat squeaks when turning, it is the bearing at the bottom. Lubricating it is very simple: to do this, you need to turn the chair upside down, remove the stop and washer that hold the gas lift in the center of the crossbar. After this, you can easily pull out the cross, exposing the gas lifting mechanism. There is no need to disassemble it anymore, it is better to clean and lubricate it. If the device fails, it must be completely replaced.

The instructions for any office furniture indicate that lubrication and inspection of the mechanism, as well as tightening of connecting elements, should be carried out every six months.

Repairing a dry wooden chair

Wood can dry out over time if there is not enough moisture in the room or if the chair is permanently placed near a heat source. In this case, the dimensions of the parts are reduced, the adhesive joints become movable around the legs and crossbars. At the same time, the ends of the elements are still firmly attached to the glue, so the integrity of the structure is not compromised.

Methods for eliminating defects:

• remove the element from the seat and re-glue it;
• place the wedge in the slot next to the part.

The leg or crossbar is removed from the hole; if the joint is strong, steam is used. The nest is thoroughly cleaned of glue, using a knife, chisel, and scrapers. After this, lubricate the landing site and the end of the part. A paper strip is wrapped around the end to increase the adhesion tightness.

Sometimes the adhesive joint cannot be separated. In this case, the cracked joints are sealed with wedges . A cut is made on the leg or side in a place close to the joint. A thin wedge is placed in it, which only protrudes slightly beyond the dimensions. Use waste of any wood. The part will slightly widen the end of the crossbar, resulting in a strong connection. Glue is injected under the tenon.

During the gluing period pressure is applied so that the joint dries in the correct position. The clamps are tightened tightly for 12 - 14 hours, but do not overload - a large amount of glue will leak out. The chair should not be warped at this time, so that subsequent loading does not lead to the destruction of the chair elements or connecting seams.

In complex structures with supports, when the frames are inserted into the legs, all the dried elements and the frame are disassembled in order to glue the joints. If it is difficult to disassemble the entire chair, work alternately with each corner.

Design features

Before you begin repairing a computer chair, experts recommend carefully studying the types and design features of such products. In specialized stores you can see the following models of computer chairs, which have individual design features:

• for the manager - a five-beam hollow cylindrical base, a multi-block for adjusting back resistance, seat depth and roll level;
• for employees – light weight, multi-block adjustment of seat height, armrests and backrest angle;
• for guests - four legs, a comfortable seat and backrest.

Despite the variety of models, all computer chairs have a similar design, which consists of a number of components.

A five-point cross is a plastic or metal part that serves as a support for the entire structure.

Rollers are iron or polymer parts that are installed along the edges of the base. The maximum number of rollers is 5. A distinctive feature is the presence of metal fasteners and a hinge.

Preventive measures

What can I do to prevent my new bed from squeaking? A fairly common problem, the following recommendations will help you get rid of it. Preference should be given to beds made from expensive natural wood. The most durable and durable:

• Oak is practical and durable, with a beautiful pattern, it is suitable for any interior;
• mahogany – noble color, original appearance and high quality. Products made from mahogany are moisture resistant and not exposed to ultraviolet rays. The furniture emits an unobtrusive aroma that repels various insects;
• rosewood - luxury furnishings are quite expensive. The products have exclusive qualities. By rubbing the wood a little, you can feel the delicate aroma of violet. High-quality pieces of furniture will delight the owners for a long time.

Pay attention to the frame - the elements must be firmly attached and should not dangle. It is better to choose a mattress with separate blocks

They are stronger and more durable. Over time, it must be turned over so that the load is evenly distributed over its surface.

When installing your new bed, try to position it as level as possible. An uneven load on the bed frame and base will subsequently lead to loosening and distortion of parts, and as a result, creaking. All fasteners must be tightly tightened so that the bed forms a solid structure. Metal products will be more durable. Another plus is their cost. Metal beds are cheaper than wooden ones. They also look beautiful and will suit almost any setting. Forged beds do not creak, they look stylish and elegant.

All wooden beds begin to creak during use. You can get rid of the annoying sound at home, the main thing is to correctly determine the cause and choose the appropriate solution.

Other options

You shouldn’t rule out other reasons why the sofa creaks. How to fix the problem if we are talking about a folding structure? First, you should examine the state of the transformation mechanism, which could have failed. There are two ways to fix the problem - completely replacing the elements or fixing them.

Uneven supports are another likely explanation for the “musicality” of a piece of furniture. To fix the problem, they need to be adjusted in height. To do this, you need to stock up on plastic plugs or other sufficiently stable material at hand.

Friction of metal parts can also cause the sofa to squeak. If we are talking about an iron structure, lubrication of the elements will help correct the situation. To do this, use machine oil. It must be carefully dripped along the joints of the fastenings

It is important that the oil does not affect the furniture upholstery or its wooden parts. Adding lubricant should only be started after preliminary preparation.

The surface should be thoroughly cleaned of grease stains and furniture.

Sofa repair is a task that anyone can handle. Don't rush to the store for new furniture if your old piece makes an annoying sound.

The sofa consists of a frame structure, spring blocks, filling, upholstery and a folding mechanism. Creaking and other extraneous sounds can occur in both metal and wooden parts of the frame. The reasons why a sofa creaks can be different. To get rid of them, first determine the area from which they are emitted, and then establish the signs of their occurrence.

An unpleasant creaking sound most often occurs due to the friction of homogeneous elements made of metal (for metal creaks) or wood (for wooden ones), which appear due to wear and tear of the sofa structure. Very often sounds are heard at the joints, in spring blocks. The reason may also be poorly tightened bolts on the fasteners. Let's look at how to eliminate a creaking sofa in more detail, since it will depend on the type of design and type of product.

How to lubricate the zipper?

If you notice that the lock has stopped sliding smoothly, you should take care of the product. Any sudden movement leads to damage to the material.

There are 2 types of zippers: metal and plastic. The first option is used for shoes, bags, and thick outerwear. And the second is suitable for light materials (jackets, dresses, etc.).

It is possible to restore the slippery property of zippers by the following means:

• Sunflower oil, lard. Both products are suitable for a metal lock on a leather product.
• Camphor. This method has a drawback - after the procedure, a stain may remain on the item. And therefore you should stock up on a thin brush or cotton swabs.

• Pencil. It is best used with a zipper sewn to thin material. Unlike previous options, there is no risk of leaving greasy stains. Use both graphite and regular pencils. It is important that the texture of the lead is as soft as possible.

• Paraffin candle. The component will save the plastic fastener. After the manipulations, the slider will be like new.

• Soap. Also used for plastic lock. If you choose this option, then manipulations must be performed with dry soap.
• If we consider unusual methods, then even a colorless lip balm can save the slider. Only extreme caution should be exercised during application.

When should you go to the salon?

If you understand that it is impossible to eliminate the squeak without replacing parts, then it is best to leave this work to professionals. Selecting a suitable and high-quality part, welding and digesting parts of the structure is beyond the capabilities of a beginner or a person who has never done this. During the repair process, due to inexperience, the integrity of the seats and other parts of the car can be damaged. It should be noted that eliminating squeaks without the proper knowledge and experience can lead to injury to the driver himself. If you are not sure that you can handle the task yourself, then it is better not to risk it and entrust this task to experienced mechanics.

Prevention

In order not to search on numerous sites and ask friends what to do if your computer and office chair squeak, it is better to prevent this problem in advance. You cannot neglect the rules for operating such furniture, believing that it is made reliably, and if something is wrong, the fault lies with the manufacturer.

Chairs with moving parts must be able to be used correctly:

1. They should not be turned, rocked or tilted too far back unnecessarily. Also, don’t spin around in your chair like on a carousel.
2. It is important to remember that there are weight restrictions that such furniture can withstand, so obese people need to choose special and more durable models.

Features of gas lift operation

First of all, I note that the malfunction indicated in the title always indicates a breakdown of the gas lift - a unit that performs the following functions:

• Creates a cushioning effect when you sit down. This relieves stress from the spine and makes sitting on the chair more comfortable. The element dampens the impact effect that often occurs when landing on rigid structures.
• Raises or lowers the seat due to a special mechanism. This allows you to adapt the design to people of different heights and adapt it to different types of work. For example, writing requires a different position than working at a computer, and thanks to the gas lift, adjustments are made in literally a matter of seconds.
• Provides rotation of the chair around its axis. This function is also provided by a pneumatic cartridge (this is also the name of the mechanism in question). Thanks to this element, you can rotate 360 ​​degrees in both directions without any restrictions.

Thanks to the gas lift, the chairs become much more comfortable and functional

The design is a steel cylinder, inside of which a rod with a piston moves. The cylinder is made in the form of a sealed element of a certain shape, divided into two chambers. A valve is installed in the partition between the chambers, due to which gas moves from one chamber to another.

The gas is located in two chambers - external and internal and moves depending on the opening of the valve

When the seat is fully lowered, the piston is in the up position. When you press the lever, the damper opens and the gas moves from one chamber to another, it presses on the piston, and then it goes down, while simultaneously lifting the seat up.

When the lever is lowered, the valve closes and the structure is locked in the required position. Everything is quite simple, but if you look at the system inside, you will see that it consists of many elements. The diagram below shows a cross-section of the product.

The system inside is quite complex, but this does not matter, since we will not disassemble it

Another important element is the support bearing; it is located at the end of the rod and ensures free rotation of the chair in both directions.

The support bearing allows the chair to rotate freely in both directions

All pneumatic chucks are divided into classes, which depend on the thickness of the steel used for the elements inside which there is gas under pressure:

• Class 1 - 1.2 mm.
• Class 2 - 1.5 mm.
• Class 3 - 2.0 mm (designed for loads up to 120 kg).
• Class 4 - 2.5 mm (used on chairs that can support up to 150 kg).

The higher the class, the stronger and more durable the gas lift, but also the more expensive its cost.

Another part of the mechanism is the gas lift casing. It does not perform any functions and serves for decorative purposes, covering the metal cylinder and giving the chair a more attractive appearance. Used only on plastic models; on metal ones the structure does not close.

The casing is a simple telescopic element of three plastic sections inserted into each other

Keep in mind that the gas in the housing is under very high pressure, and any damage to the integrity is dangerous to human life and health.
